There isn't currently, BUT if someone feels like writing a tiny little commandline tool you could integrate that into LBC.
See the help section on "Commandline Output and Text Contents Menu Nodes":
You can now have LBC run a commandline console tool and grab the output of it to make menus on the fly.
Essentially just make a commandline tool that outputs one or more lines containing the date, time, etc. and then add the commandline tool as a "CommandLineOutput" node.
If you want to get fancy you can let the generated items PASTE into the last application when selected, and give them custom icons.
